What is the difference between key and code?
Key describes the produced character or action, while code identifies the physical keyboard position. For example, the same physical key code may produce a different character under another layout.

HelpFrequently asked questions
What does keyboard location mean?
Location distinguishes standard, left, right, and number-pad versions of keys. It is especially useful for Shift, Control, Alt, Enter, and number keys.
What is detected rollover?
Detected rollover is the largest number of keys the browser reported as held at the same time during this test. Operating systems and browsers may intercept some combinations.
Why do some browser or media keys not appear?
The operating system or browser can reserve shortcuts, function keys, media controls, and secure combinations before a web page receives them.
Does the tester change my keyboard settings?
No. It displays keyboard events received by the page and does not change the operating-system layout, repeat speed, remapping, or hardware configuration.
